Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of sewage treatment, in particular to a sewage treatment equipment for a silicon steel sheet production line. BACKGROUND

[0002] With the development of industrialization and the expansion of cities, sewage treatment has become an important problem that must be solved in cities. Common sewage treatment methods include physical penetration, biological degradation, chemical treatment, etc. During the production of silicon steel sheets, a large amount of sewage is usually generated. The existing silicon steel sheet sewage usually contains a large amount of silt impurities, so that during sewage treatment, filtration treatment is usually required before adding chemicals for precipitation.

[0003] When filtering and precipitating sewage, a filter screen is usually used. During filtration, the high-speed flowing sewage will cause a large impact on the filter screen, and impurities will accumulate on the filter screen, causing the filter screen to be blocked, affecting the service life of the filter screen, and during the addition of chemicals for flocculation and precipitation, the chemicals need to be mixed with the sewage by stirring. However, firstly, a large torque motor is required to drive the blade to rotate, which increases the cost of the device.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. Wastewater is treated by sedimentation in the pretreatment chamber, and the sediment is allowed to settle. Impurities are directly discharged through the sewage discharge structure without the need for filtration. This reduces the use of filter screens, prevents filter screen clogging and impact-induced problems, and extends the service life of the device. In addition, the sedimentation treatment can also stratify the wastewater, with oil floating on top and solid impurities settling down. Only the middle wastewater is extracted, thereby improving the efficiency of wastewater treatment. Multiple chambers work in sequence to realize a flow-type wastewater treatment operation, improving work efficiency.

[0018] 2. The wastewater and chemicals are directly mixed through the dosing structure, and the dosage is automatically adjusted according to the wastewater flow rate, thus eliminating the need for stirring and ensuring uniform mixing. Furthermore, it can also play a certain mixing role during aeration, accelerating the reaction speed. Therefore, there is no need to install a separate stirring structure, reducing the operating cost of the device and improving work efficiency.

[0019] 3. The separation chamber and pumping structure allow the wastewater after aeration to be left to stand and be pumped out, enabling continuous aeration within the aeration chamber. This accelerates the wastewater treatment efficiency of the device, and the pumping structure effectively separates solid impurities, ensuring the optimal wastewater treatment effect.

[0039] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] like Figures 1 to 10As shown in the figure, this disclosure proposes a wastewater treatment device for a silicon steel sheet production line, comprising: a treatment tank 101, wherein the treatment tank 101 is provided with a pretreatment chamber 102, an aeration chamber 103 and a separation chamber 104, wherein the pretreatment chamber 102 is provided with an inlet structure, a discharge structure and a sedimentation structure, the discharge structure corresponding to the sedimentation structure; a dosing structure, wherein the dosing structure is installed on the upper side of the aeration chamber 103, the dosing structure corresponding to the pretreatment chamber 102, the aeration chamber 103 is provided with an aeration structure, the aeration structure being provided with an anti-clogging structure; and a pumping structure, wherein the pumping structure is installed in the separation chamber 104, the pumping structure corresponding to the pretreatment chamber 102.

[0041] The water inlet structure includes: a water inlet pipe 201; a first sedimentation chamber 202 is provided in the pretreatment chamber 102; one end of the water inlet pipe 201 is located at the bottom of the first sedimentation chamber 202; a first drain outlet 204 is provided on one side of the first sedimentation chamber 202; a first blocking plate 205 is slidably fitted in the first drain outlet 204; a first rodless cylinder 203 is fixed on the treatment tank 101; and the output end of the first rodless cylinder 203 is fixedly connected to the first blocking plate 205.

[0042] Specifically, wastewater is sent into the first sedimentation chamber 202 through the inlet pipe 201. Heavier solid impurities in the wastewater settle. As the water level rises, water and oil rise until they reach the first connecting port 301, and then enter the second sedimentation chamber 303 for settling. The first rodless cylinder 203 can be activated periodically, causing the first blocking plate 205 to slide upward, thereby opening the first sedimentation chamber 202 and cleaning the impurities at the bottom of the first sedimentation chamber 202. There is no need to use a filter screen for filtration; the stratification is achieved solely by the difference in density, which can achieve a good solid-liquid separation effect. This prevents damage to the filter screen caused by the impact of high-velocity wastewater, avoids clogging, reduces the frequency of cleaning, and improves work efficiency.

[0043] The sedimentation structure includes: a second sedimentation chamber 303, which is located within the pretreatment chamber 102. Multiple first connecting ports 301 are provided between the second sedimentation chamber 303 and the first sedimentation chamber 202. A first electric valve 302 is installed within each first connecting port 301. Multiple partition plates 316 are fixed within the second sedimentation chamber 303. The partition plates 316 divide the second sedimentation chamber 303 into multiple chambers. Each first connecting port 301 corresponds to one of the multiple chambers. A pumping structure is installed on the second sedimentation chamber 303, corresponding to both the chambers and the dosing structure.

[0044] Specifically, as the water level rises in the first sedimentation chamber 202, the wastewater enters the first connecting port 301. Then, the first electric valve 302 is opened, allowing the wastewater to enter the second sedimentation chamber 303 through the first connecting port 301 for settling. As the water level in this chamber rises, the first electric valve 302 is closed, and another first electric valve 302 is opened, allowing the wastewater to enter another chamber for settling. This allows for simultaneous water addition and settling, shortening the settling time and improving work efficiency. Furthermore, the first sedimentation chamber 202 can initially remove solid impurities, and the settling in the second sedimentation chamber 303 can further remove solid impurities, improving the cleaning effect. Since the entire device does not use a filter structure, it can prevent filter clogging, improve the cleaning efficiency of solid impurities, and extend the service life of the device.

[0045] The sewage discharge structure includes: a pusher plate 309, which is slidably connected to the treatment tank 101; a cavity 305 is provided in the pretreatment chamber 102, which is connected to the first sedimentation chamber 202; the cavity 305 is slidably connected to the pusher plate 309; a plurality of second connecting ports 304 are provided between the cavity 305 and the second sedimentation chamber 303, and the second connecting ports 304 correspond to the chambers; sludge in the second sedimentation chamber 303 flows into the cavity 305 and is then pushed out by the pusher plate 309; a driving structure and a shielding structure are installed in the cavity 305, which correspond to the pusher plate 309 and the shielding structure corresponds to the second connecting ports 304.

[0046] Specifically, when it is necessary to clean the impurities in the first sedimentation chamber 202, the second rodless cylinder 306 is activated, which pushes the push plate 309 out of the cavity 305. At this time, the first sedimentation chamber 202 is blocked by the shielding structure. The first rodless cylinder 203 drives the first blocking plate 205 to open the first drain port 204, thereby discharging the solid impurities through the push plate 309. The shielding structure also prevents the clear liquid above from flowing downward and being pushed out as well. This allows for cleaning impurities while adding water, thereby improving work efficiency and reducing water waste.

[0047] The driving structure includes: a second rodless cylinder 306 and a third rodless cylinder 307; both the second rodless cylinder 306 and the third rodless cylinder 307 are fixed in the cavity 305. The output end of the second rodless cylinder 306 is fixedly connected to a push plate 309. The push plate 309 has multiple third connecting ports 310. Multiple first blocking blocks 311 are fixed in the cavity 305, and the first blocking blocks 311 correspond to the third connecting ports 310. The blocking structure includes a first baffle 308 that slides in the cavity 305. The first baffle 308 is fixedly connected to the output end of the third rodless cylinder 307. The sewage discharge structure also includes: a second sewage outlet 312. The second drain outlet 312 is located at the bottom of the cavity 305. The second drain outlet 312 and the first drain outlet 204 are located on both sides of the push plate 309. A sliding groove 314 is provided in the second drain outlet 312. A second blocking plate 313 is slidably fitted in the sliding groove 314. A plurality of first springs 315 are fixed between the second blocking plate 313 and the groove wall of the sliding groove 314. The solid impurities at the bottom of the second sedimentation chamber 303 are pushed out through the first drain outlet 204 by the push plate 309. The solid impurities in the second sedimentation chamber 303 flow into the cavity 305 through the third connecting port 310. The push plate 309 is reset and pushes the impurities out through the second drain outlet 312.

[0048] Specifically, activating the second rodless cylinder 306 moves the push plate 309, which in turn moves the first baffle 308 via the third rodless cylinder 307. When the first baffle 308 moves, it blocks the first sedimentation chamber 202, preventing wastewater above it from being pushed out and wasting water. It also allows for simultaneous water addition and cleaning of impurities at the bottom, improving efficiency. Simultaneously, the first baffle 308 no longer blocks the second connection port 304, allowing impurities in the second sedimentation chamber 303 to pass through. Water flows into the cavity 305 through the connecting port 304. When the push plate 309 is reset, it can move the second blocking plate 313, thereby opening the second drain port 312 and allowing impurities to be discharged through it. Furthermore, the sliding of the push plate 309 will cause the first blocking block 311 to no longer block the third connecting port 310, allowing water in the cavity 305 to flow into the first sedimentation chamber 202 below the first baffle 308. This reduces the concentration of solid impurities, lowers the difficulty of cleaning solid impurities, and improves cleaning efficiency, thereby increasing the working efficiency of the device.

[0049] The pumping structure includes: a water pump 401, which is fixed on the treatment tank 101. The water pump 401 has an inlet head 402 fixed at its inlet end. Multiple first pumping pipes 403 are fixed on the inlet head 402. The multiple first pumping pipes 403 correspond one-to-one with multiple chambers. A second electric valve 404 is installed on the first pumping pipe 403. The water pump 401 has a drain pipe 405 fixed at its outlet end. The drain pipe 405 corresponds to the dosing structure.

[0050] Specifically, starting the water pump 401 allows the wastewater in the middle section after settling to be extracted through the water pump 401 and the first pumping pipe 403. At this time, the oil at the top and the solid impurities at the bottom can remain in the chamber, thus achieving a better separation effect. Compared with filtration, settling separation and extraction can separate more types of impurities at once, thereby improving work efficiency, reducing the number of steps in wastewater treatment, and reducing workload. The water pump 401 extracts the wastewater through the first pumping pipe 403 and then sends it into the drain pipe 405.

[0051] The dosing structure includes a dosing tank 501, which is fixed to the treatment tank 101. A connecting pipe 502 is fixed to the bottom of the dosing tank 501 and is connected to a drain pipe 405. A ball bearing 503 is rotatably fitted inside the connecting pipe 502. Multiple grooves 504 are formed on the periphery of the ball bearing 503. The dosing tank 501 is located above the aeration chamber 103. A second baffle 505 is fixed to the top of the aeration chamber 103 and corresponds to the water pump 401. The water pump 401 draws out wastewater, adds chemicals, and then sprays it out from the drain pipe 405. The sprayed wastewater comes into contact with the second baffle 505.

[0052] Specifically, when sewage is sent into the drain pipe 405, the large water flow will impact the rolling ball 503. The friction between the sewage and the rolling ball 503 will cause the rolling ball 503 to rotate, thus bringing the rolling ball 503 into contact with the agent. Some of the agent adheres to the surface of the rolling ball 503. As the rolling ball 503 rolls, it comes into contact with the sewage, thus dissolving the agent in the sewage. The flow rate of the sewage can be controlled by the water pump 401, so that the sewage and the agent can be mixed more thoroughly during the sewage addition stage, thus eliminating the need for the stirring step. This not only ensures the mixing effect of the sewage and the agent, but also improves work efficiency and prevents impurities from adhering to the fan blades, which would increase the difficulty of stirring.

[0053] The aeration structure includes: a jet seat 601, which is fixed inside the aeration chamber 103 and located below the second baffle 505. Multiple jet pipes 602 are fixed on the jet seat 601 and are connected to the jet seat 601. An air inlet pipe is fixed on one side of the jet seat 601. Multiple air holes 603 are opened on the periphery of the jet pipes 602. Limiting blocks 604 are fixed inside the air holes 603. A second blocking block 606 is elastically fitted inside the air holes 603. The periphery of the second blocking block 606 is a sloped structure. A second spring 605 is fixed between the second blocking block 606 and the limiting block 604.

[0054] Specifically, during aeration, gas is sent into the jet seat 601 through the air inlet pipe, and then the gas enters the jet pipe 602. The greater air pressure pushes the second block 606 outward, causing the second spring 605 to be stretched. A gap is created between the inclined structure and the air hole 603, forming an air passage, which allows gas to be sent into the sewage. When the aeration stops, the greater water pressure will squeeze the second block 606, thereby blocking the air hole 603 and preventing sewage from entering the air hole 603 and causing blockage. This ensures smooth air intake and prevents water from entering the jet pipe 602.

[0055] The pumping structure includes: a float plate 703, which is slidably fitted within a separation chamber 104; a fourth connecting port 701 is provided between the separation chamber 104 and the aeration chamber 103; a third electric valve 702 is installed in the fourth connecting port 701; a second pumping pipe 705 is fixed on the float plate 703; a fourth electric valve 706 is fixed at the end of the second pumping pipe 705; a limiting plate 704 is fixed at the bottom of the separation chamber 104, and the limiting plate 704 is located above the fourth connecting port 701; a third sewage outlet 707 is provided on one side of the separation chamber 104, and a third blocking plate 708 is installed in the third sewage outlet 707.

[0056] Specifically, opening the third electric valve 702 allows the aerated wastewater to be sent into the separation chamber 104 for settling. At this time, the water level rises, which can lift the float 703. Wastewater can continue to be added to the aeration chamber 103 for aeration, reducing waiting time and greatly improving work efficiency. After settling in the separation chamber 104, water can be pumped directly through the second pumping pipe 705 until the float 703 is limited by the limiting plate 704. The limiting plate 704 not only prevents the second pumping pipe 705 from pumping out the bottommost impurities, but also prevents the float 703 from being too low to rise when water is introduced, thus ensuring the settling effect.

[0057] Workflow: Wastewater is fed into the first sedimentation chamber 202 through the inlet pipe 201. Heavier solid impurities in the wastewater settle. As the water level rises, water and oil rise until they reach the first connecting port 301, thus entering the second sedimentation chamber 303 for settling. Wastewater in the first sedimentation chamber 202 enters the first connecting port 301 as the water level rises. Then, the first electric valve 302 is opened, allowing wastewater to enter the second sedimentation chamber 303 for settling. As the water level in this chamber rises, the first electric valve 302 is closed, and another first electric valve 302 is opened, allowing wastewater to enter another chamber for settling. This allows for simultaneous water addition and settling. To shorten the settling time, when it is necessary to clean the impurities in the first sedimentation chamber 202, the second rodless cylinder 306 is activated. The second rodless cylinder 306 pushes the push plate 309 out of the cavity 305. At this time, the first sedimentation chamber 202 is blocked by the shielding structure. The first rodless cylinder 203 drives the first blocking plate 205 to open the first drain port 204, thereby discharging solid impurities through the push plate 309. Activating the second rodless cylinder 306 moves the push plate 309, and the third rodless cylinder 307 moves the first baffle 308. When the first baffle 308 moves, it can block the first sedimentation chamber 202, preventing impurities from being discharged. The wastewater is pushed out, which wastes water. However, water can be added while cleaning impurities at the bottom, improving work efficiency. Simultaneously, the first baffle 308 no longer blocks the second connecting port 304, allowing impurities in the second sedimentation chamber 303 to flow into the cavity 305 through the second connecting port 304. When the push plate 309 resets, it moves the second blocking plate 313, opening the second drain port 312 to discharge impurities. Furthermore, the sliding of the push plate 309 causes the first blocking block 311 to no longer block the third connecting port 310, allowing water in the cavity 305 to flow into the first sedimentation chamber 202 below the first baffle 308, thus reducing the concentration of solid impurities and simplifying the cleaning process. To reduce the difficulty, the water pump 401 is started, and the wastewater in the middle after settling is pumped out through the water pump 401 and the first water suction pipe 403. At this time, the oil at the top and the solid impurities at the bottom can remain in the chamber, thus achieving a better separation effect. When the wastewater is sent into the drain pipe 405, the large water flow will impact the rolling ball 503. The friction between the wastewater and the rolling ball 503 will drive the rolling ball 503 to rotate, so that the rolling ball 503 comes into contact with the agent. Some of the agent adheres to the surface of the rolling ball 503. As the rolling ball 503 rolls, it comes into contact with the wastewater, so that the agent dissolves in the wastewater. When aeration is performed, the gas is sent into the jet seat 601 through the air inlet pipe, and then the gas enters the jet pipe 602.The higher air pressure pushes the second block 606 outward, stretching the second spring 605. A gap is created between the inclined structure and the air hole 603, forming an air passage that allows gas to be introduced into the wastewater. Opening the third electric valve 702 allows the aerated wastewater to be sent into the separation chamber 104 for settling. The rising water level at this time can lift the float 703, allowing more wastewater to be added to the aeration chamber 103 for continued aeration, reducing waiting time and significantly improving efficiency. After settling in the separation chamber 104, water can be directly pumped out through the second pumping pipe 705 until the float 703 is stopped by the limiting plate 704, thus achieving wastewater treatment for the silicon steel sheet production line.
